Tinny sounding speakers (and headphones)

[kulivontot]

Hi, I'm having this problem recently with my T60, where the left speakers makes this really tinny sounding noises when sounds play. Most of the time it's fine, but every once in awhile, I will hear an IM or some other sound where it sounds really distorted and metallic. I thought it might have been a blown speaker at first, but the same thing happened when I had headphones plugged in too, so it sounds like it may be a driver/hardware issue. Anyone else have something like this happen?
